1. Fixed "always syslog" mode Used to force log output to syslog even when

   not daemonized: log output would be repeated (once with a timestamp in
   the log string, once without). Now direct calls to lputs/lprintf from
   sbbscon.c won't go to syslog (in this mode), but I think that's okay.
2. Change the prompt when terminating the servers: replace the ?=help and
   colon implying you can enter commands with just "Termianting..." since
   you can't actually type commands while a terminate is in progress.
3. Output the inactivity timeout values when waiting for servers to
   terminate (e.g. because they'res till in use).
4. Report IP addresses in square-brackes in the client ('c' command) output
   to differentiate from hostnames.
